Description
Astah UML gives software teams and students a focused tool for UML 2.x modeling. Class, use case, sequence, activity, state machine, component, and deployment diagrams are all available, together with mind maps for early brainstorming.
Every diagram is a view of a shared model, so renaming a class or changing a relationship updates it everywhere it appears.
For AI-assisted work, Astah UML offers AI Chat Copilot and AI-assisted code reverse engineering, both of which connect to OpenAI, Azure OpenAI, Claude, Gemini, or any OpenAI-compatible endpoint through your own API key. A local MCP server lets external AI agents read and work with your models, and conventional reverse engineering turns existing Java, C#, and C++ code into diagrams without an AI service.
Astah UML runs locally on Windows, macOS, and Linux.
Developer: Change Vision, Inc.
Current version: 12.0 (July 2026).
Students can use it free of charge, and a 20-day trial is available for everyone else.
Description
Diagram.now serves as a versatile diagram editing tool designed for Confluence Cloud, and it also features a complimentary browser-based editor. As a Forge-native application developed for Atlassian, it enables users to create and save diagrams directly within Confluence, eliminating the need for an external server or the hassle of creating additional accounts.
Users can design various diagram types, including flowcharts, UML, BPMN, ERD, mind maps, cloud architecture diagrams, and wireframes. Additionally, it supports importing existing projects from platforms like Visio, Lucidchart, Gliffy, Mermaid, and SQL schemas, facilitating a seamless transition for teams looking to switch tools without the need for redrawing their work.
The application is free for teams of up to 10 users, while the browser-based editor can be accessed at no cost, even without a Confluence account. Furthermore, it represents an efficient solution for collaborative diagram creation and editing, making it easier for teams to visualize their ideas effectively.
